Another aspect of color involves adding white or black to pure hues. Adding white lightens color, and the result is called a tint. Adding black darkens the color and the result is called a shade. For example, pink is a tint of red and maroon is a shade of red. Note the full color wheel includes increasingly lighter tints toward the outside and darker shades toward the center.

Shades -- in this case a rather dark shade of yellow -- have a low-key effect, making the scene more somber. Their color holds up in the middle part of the day when there is plenty of light. But they fade toward black as light decreases in the evening.

Tints--in this case the lighter yellows in the foliage and flowers -- have a brightening effect. When the sun is high and unobscured these plants may appear washed out, but later in the evening they will remain evident when the darker shades have disappeared.
